Exocrine Pancreatic Function Testing in Cystic Fibrosis

Status Active, not recruiting

Clinical Trial Summary

Purpose The purpose of this study is to develop and validate multimodal testing of exocrine pancreatic function (EPF). The investigators will be testing exocrine pancreatic function in patients with cystic fibrosis (CF). Exocrine pancreatic function and imaging will be correlated to age group, genotype, nutritional status and quality of life. Earlier detection of exocrine pancreatic failure in the non classical form of cystic fibrosis may be of therapeutically benefit.

Hypotheses Endoscopic short test can be applied in diagnosing and monitoring exocrine pancreatic function in patients with cystic fibrosis.

New functional testing of exocrine pancreatic function is superior to traditional testing with fecal elastase.

MRI and ultrasound methods can give volume output estimate in cystic fibrosis patients.

Contrast enhanced ultrasound can quantify reduced or delayed pancreatic perfusion and parenchymal changes in cystic fibrosis patients.

Elastography/ CEUS can be used in prediction and monitoring of fibrosis development and development of hepatocellular carcinoma in the liver of cystic fibrosis patients.

Immunohistochemical quantification of secretin/ cholecystokinin (CCK) producing cell in duodenum can be utilized as a model hormonal signaling in cystic fibrosis patients with exocrine pancreatic function.

Clinical Trial Description

Study design: Observational, cohort studies.

Patient characterization: Age, gender, and Genetic status from electronical records.

Exocrine function testing (EPF): Secretin stimulated ultrasound and short endoscopic secretin test (EST). Faecal Elastase.

Imaging: Transabdominal ultrasound of the liver and pancreas. secretin stimulated MRI. Contrast enhanced ultrasound (CEUS) of the pancreas using SonoVue contrast.

Endpoints:

Study 1: Exocrine pancreatic function by duodenal bicarbonate/ Enzymes related to Genetics and F elastase.

Study 2: Ultrasound parenchymal changes of the pancreas related to Genetics and EPF.

Study 3/4: Pancreatic secretion by ultrasound, MRI and EST related to EPF Study 5; Perfusion of the pancreas by CEUS related to EPF

Study 6: Genotype-phenotype conciderations of the CF pancreas. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
